Reslizumab and mepolizumab for moderate-to-severe poorly controlled asthma: an indirect comparison meta-analysis

Aim: A systematic literature review and network meta-analysis assessed the efficacy and safety of reslizumab 3.0 mg/kg and mepolizumab 100 mg. Materials & methods: Eligible studies evaluated reslizumab and mepolizumab in patients with inadequately-controlled severe eosinophilic asthma. Using a Bayesian network meta-analysis, 95% credible intervals and posterior probabilities were reported. Results: Of 19 indirect efficacy comparisons performed in base-case (Global Initiative for Asthma 4/5 patients with ≥2 exacerbations in the previous year) and overall populations, significant differences favoring reslizumab were observed for severe exacerbations, FEV₁ at 4 weeks and eosinophil counts at 4, 16 and 24 weeks, with no other significant differences including risk of adverse events. Conclusion: Indirect comparison of reslizumab and mepolizumab largely showed no significant differences in efficacy or safety.
